4short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is the equations of motion?Show answer
For projectiles, treat the horizontal and vertical motions separately: the horizontal velocity is constant (no horizontal force) and the vertical motion has acceleration downward.
